Subject: [PATCH 11/13] ARM: dts: stm32: fix LTDC port node on STM32 MCU ad MPU

Running "make dtbs_check W=1", some warnings are reported concerning
LTDC port subnode:

/soc/display-controller@...01000/port:
unnecessary #address-cells/#size-cells without "ranges" or child "reg"
property
/soc/display-controller@...01000/port: graph node has single child node
'endpoint', #address-cells/#size-cells are not necessary

Signed-off-by: Alexandre Torgue <alexandre.torgue@...s.st.com>
